UNITED STATES PATENT OFFICE LEONARD BAILEY, OF HARTFORD, CONNECTICUT.

RIBBON FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 472,847, dated April12, 1892.

Application filed April l0, 1888.

To all whom it may concern:

Be it known that I, LEONARD BAILEY, of Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Ribbons for TypelVriting Machines, of which thefollowing is a full, clear, and exactdescription, whereby any oneskilled in the art can make and use the same.

My invention relates' to the class of ribbons that are speciallyprepared for use on a typewriting machine by being treated or saturatedwith an ink that remains moist for a considerable time; and myobjectisto providearibbon of this class that will have the ends iinpervious tothe ink used in treating the ribbon and thus leave such ends after theAribbon has been inked in proper conditionfor handling without danger ofsoiling the hands.

My improvement consists in a type-Writer ribbon having one or both endsprepared with a material that renders it impervious to the ink used tocoat or load the ribbon, as more particularly hereinafter described,andpointed out in the claim.

Referring to the drawing, the figure repersents a type-Writer ribbonrolled or folded up and with one end extended and illustrating themethod of embodying my improvement in a ribbon.

The type-Writer ribbons are made of any suitable and desirable material,as linen of a tine grade or silk, and a strip of any desired length andwidth is saturated or loaded with the proper supply of an ink that willremain moist fora considerable length of time. Such a ribbon is to beplaced on a type-Writing machine by hand, and in the handling theoperator is put to great inconvenience and loses considerable time bythe ink staining the fingers and hands when such ribbon is covered withink for the whole length.

Serial No. 270,162. (No model.)

In the accompanying drawing, the lettera denotes a type-writer ribbon ofany suitable fabric or material, the greater portion thereof being inkedin any usual manner. The ends b b', however, before such inking arecoated or treated with a preparation thatwill not be dissolved by theink and that prepares the substance of the ribbon so that but little ornone of the ink can remain on this prepared surface. I find it possibleto use a solution of gum shellac in alcohol and to apply this to one orboth ends of the ribbon Wit-h a brush. The ribbon,when thus prepared, isthen inked, and although this prepared end may rest in contact with themain body of the ribbon when the latter is folded or rolled up in theusual manner for storage or transportation, but little, if any, of theink remains upon the prepared ends of the ribbon. Such a ribbon iscomparatively clean and is easily handled Without soiling the hands ofthe operator in putting it into or removing it from the machine. y

I do not limit myself to the use of anyspeciflc gum or material forpreparing the ends of the ribbon for the purpose herein described andclaimed, as any equivalent gum or other soluble substance dissolved in avehicle that is impervious to the ink will be sufficient to enable myinvention to be practiced.

I claim as my invention- As an improved article of manufacture, atype-Writer ribbon having one or both ends coated or saturated with amaterial thatsrenders theJ parts so treated impervious tothe ink usedforinking the ribbon, all substantially as described. f
